Title: Disc brake, more especially for rail vehicles
IPC: F16D65/56
Filed: 1968-11-26
Abstract: 1,219,490. Disc brakes. KNORR BREMSE G.m.b.H. 26 Nov., 1968 [2 Dec., 1967], No. 56130/68. Heading F2E. A disc brake more especially for rail vehicles comprises a U-shaped stirrup 4 (Fig. 1) which, straddles the rim of a brake disc 1 and of which one arm 5 carries a brake shoe 2, while its other arm supports for displacement perpendicularly of the brake disc a stem portion 8 carrying at its forward end the other brake shoe 3, there being means for applying to the rearward end of the stem portion 8 a brake applying force, said means including a wedge-shaped pressure element 12 which is introduced between the rearward end of the stem portion and a fixed wall on that arm 6 of the stirrup 4 carrying said stem portion, said pressure element 12 being displaceable by a piston rod 13 of a brake cylinder 14 also carried by the stirrup 4. Manual and automatic adjustment.-In a preferred embodiment (Fig. 2) a threaded spindle 50 carrying a brake shoe 52 is screwed into a nut 49 which slides in a sleeve 26 together with a ring 59 and thrust element 44. Manual adjustment is effected by withdrawing a pin 77 from one of four blind holes 83 in spindle 50 and then rotating a hand wheel 71 to screw the spindle 50 in the nut 49. The gap between hand wheel 71 and sleeve 26 is bridged by a flexible collar 74 to prevent the ingress of dirt. Automatic adjustment is effected by studs 88 fixed into sleeve 26 and projecting into sloping grooves 86 in ring 59, the clearance between the studs and the sides of the grooves in the axial direction 92 being equal to the normal brake clearance. Teeth 61 on ring 59 are urged into engagement with teeth 58 on nut 49 by a spring 62. A oneway ball-type clutch (90) (Fig. 3, not shown) is disposed between the nut 49 and that part of the thrust element 44 which surrounds it, and element 44 is prevented from rotating by a stud 46 projecting into a groove 45. On applying the brake, the ring 59 moves with the nut 49 and spindle 50 in the direction 92 until the studs 88 engage walls of the grooves 86. If there is excessive clearance, further movement turns the ring 59 so that the teeth 61 are disengaged from the teeth 58, the nut 49 being prevented from turning by the clutch (90). On releasing the brake the nut 49 moves back until the teeth 58, 61 re-engage and the ring 59 moves back until the studs 88 engage the opposite walls of the grooves 86 whereupon the ring 59 and nut 49 are turned in a direction which screws out the spindle 50 by an amount of adjustment which is automatically preselected by the rotation of the ring 59 on initiating the brake action.

A polyphase motor-operated actuator 20 having a reversing starter circuit which forms an integral part of the actuator assembly, has a control circuit 31 which prevents energization of the starter circuit if the phase sequence of the supply A, B, C is incorrect. The control circuit comprises a relay 19, the voltage across which is made dependent upon the phase sequence by its being star connected with a resistor or other impedance 15 and a capacitor 18. A contact 32 of the relay is closed if the phase sequence is correct, thus permitting operation of forward or reverse contactors 27, 29 by push-buttons 38, 41. 37 and 44 are limit switches and the object of the invention is to prevent wrong rotation of the motor, when the limit switches would be ineffective. The starter circuit is energized from the two phases not connected to the relay 19 so that the motor cannot be started unless the supply is present on all three phases. The relay may also operate an indicator lamp and to accommodate various supply voltages the resistor 15 may be tapped and the starter circuit energized via a tapped transformer or a separate supply. The relay may be electromagnetic, thermal, thermionic or semi-conductor type, the contactors 27, 29 may be replaced by semi-conductor switches, the limit switches may respond to position and/ or torque, there is an overload switch 34, and the actuator may operate a valve.

Abstract: 1410960 Master cylinders; boosters ALFRED TEVES GmbH 14 Dec 1972 [24 Dec 1971 (2)] 57698/72 Heading F2F In a master cylinder for a dual circuit braking system in which fluid pressure from a reservoir 12 provides a power boost for a master piston 17 supplying hydraulic fluid to a first circuit 16 and directly supplies hydraulic pressure to a second circuit 15 pressurization of one circuit is possible if the other circuit fails without excessive downtravel of a brake pedal 14 taking place. On actuation of brake pedal 14 a control piston 11 is moved to firstly close a port 39, leading via chamber and port 65 to a return reservoir 38, and then to open a valve 13 via tappet 29 to allow fluid pressure from reservoir 12 to pass via bore 35 to a chamber 24, and when bores 23, 22 provided in an auxiliary piston 18 and piston 11 respectively are aligned to permit fluid to pass into bore 58, where it passes into a chamber 48 to act on piston 17 thereby providing a boost. Pressure also acts via a bore 21 on the brake pedal to provide a reaction and further passes to circuit 15 by way of bore 25 and chamber 26. If circuit 16 fails fluid pressure acting on piston 17 causes it to engage the cylinder bottom and during the movement liquid is drawn into a chamber 47 from reservoir 38 via port 46. Continued leftward movement of piston 18 causes a sleeve 45 thereof to cover port 46 so that chamber 47 is sealed. Further leftward movement of piston 18 is prevented by the incompressibility of the fluid in chamber thereby eliminating excessive travel of the brake pedal. If circuit 15 fails an end surface 27 of piston 11 abuts the step formed in piston 18 between the bore 58 and chamber 61 to mechanically move piston 17 to pressurize circuit 16.
